LibKF6Breeze Icons and KIconLoader

[Jonathan Riddell]

Has anyone had issues with Breeze loading using Frameworks 6.2 or
master building the libKF6BreezeIcons.so.6 library in breeze-icons.
In neon we found that the icons did not load in Plasma and System
Settings and other QML apps.  The Breeze theme was not available for
selection in System Settings but Breeze Dark was available for
selection.

This only happened in the packaged build.  A manual build was fine.
Building the package and copying the library in manually from the
build was fine.  But building the package and copying the library in
manually from the final package broke it.  So there's something about
the way the .deb packaging gets made that seems to break a path or
some other aspect of the library.

The error on output from apps when using the broken library is
"kf.config.core: Created a KConfigGroup on an inaccessible config
location :/icons/breeze/index.theme Icon Theme"

For now I've done a workaround of reverting to KIconLoader 6.1.
